All-Natural Pest PreventionLee Washington1As the weather becomes warmer and people travel outside more often, daring pests creep indoors to explore kitchens and pantries. It is important to know that insects and mice can contribute to the spread of germs and diseases. At the very least, these pests can damage food supplies or cause itchy bug bites. From the largest mice to the tiniest fleas, these creatures can turn a peaceful home into a crawling nightmare!2Many people, however, hesitate to use commercial sprays near children and pets or in places where they store food. The harsh chemicals in these sprays can cause serious injuries if they aren’t used properly. Luckily, there is now another choice for people who want to avoid these dangerous chemicals. The experts at Growing Garden Supply are happy to help you discover all-natural ways of keeping these creatures outdoors, where they belong.3This week, pots of peppermint and lavender plants are on sale. These herbs not only let off fragrant scents, but they also can be used to keep pests out of your home. Place a pot of lavender in the kitchen to ward off mice and use mint as an all-purpose pest remover. The scent of crushed mint leaves is unpleasant for mice, ants, and fleas. Sprinkle a few along the edge of your home to discourage pests from entering. Happily, mint leaves are completely safe for humans to eat. Try some in a cup of tea, or use them to add flavor to baked goods.4After seeing the great results from the mint and lavender plants, why not start an entire garden of plants that are unappealing to pests? Growing Garden Supply has an excellent selection of bitter cucumber seeds and garlic bulbs. Slices of cucumbers and garlic can help chase away ugly roaches and mosquitoes, and the leftovers taste wonderful in summer salads and pasta dishes.5People who are eager for an immediate fix to their pest problems might prefer a liquid spray.

What is one of the preventive measures to control storage losses in grains?Increasing the storage temperature.Fumigation using chemicals to kill pests.Allowing direct sunlight exposure without drying.Storing grains without cleaning them.

Insects can be both useful and harmful to crop plants. Insects such as bees pollinate or cross pollinate flowers. Some insects eat crops and other insects eat the insects that eat crops.Corn borers are insects that eat maize plants. A toxin produced by the bacterium Bacillus thuringiensis kills insects. Scientists grow Bacillus thuringiensis in large containers. The toxin is collected from the containers and is sprayed over maize crops to kill corn borers.A company has developed genetically modified (GM) maize plants. GM maize plants contain a gene from Bacillus thuringiensis. This gene changes the GM maize plants so that they produce the toxin.How did the scientists transfer the gene from Bacillus thuringiensis to maize plants?Genes are added only once the plant is developed by injecting enzymes are used to both remove unwanted and insert desired genes.Genes are added early on in the development process by gene splicing. Enzymes are used to both remove unwanted and insert desired genes.The genes of Bt toxin can only be added to certain plants, by spraying them with the Bt toxin gene.Genes are added only in the late development process by gene splicing. Enzymes are used to both remove and inserted genes.I DON'T KNOWSUBMIT ANSWER

InsectsBy midsummer, biting insects like mosquitoes and fleas are out in full force in most parts of the United States. Unless you plan to stay inside, you will likely head to the store to load up on bug repellents. An excellent natural alternative to chemical bug repellents is the use of essential oils. Such oils, taken from natural substances, have been used for centuries for this purpose.Essential oils repel insects because they block their sense of smell, fooling them into thinking they should go elsewhere for their meal. For example, to get rid of ants around the house, put drops of peppermint oil across the ant paths. This confuses the insects' scent trails and makes it impossible for them to find food. Similarly, you can confuse biting insects by wearing essential oils on your skin that do not allow them to sniff you out.Oils that are strong smelling work best as bug repellents. Some of the most effective are peppermint, citronella, eucalyptus, and lavender. Applying a watered-down essential oil to the warmest exposed areas of your skin (backs of the knees, behind the ears, etc.) will discourage bugs from using your skin as a landing strip. However, make sure not to use sweet-smelling or perfume-like oils.14Select the correct answer.What is the main idea of the passage? A. Insects usually have a strong sense of smell. B. Insects can be repelled through natural products. C. Natural bug repellents usually have a strong smell. D. Sweet-smelling oils can attract bugs to your skin.
